My invention relates to improvements in systems for the remote control or tel eco'm' trol of objects, such as =guns, search-hghts-,.

telescopes, pointers and the like, by con- 7 6 trolling the motors which adjust the objects.

The improved system is particularly useful for the control fi'om a of objects. which are mounted on oscillating platforms,-

for instance :the decks of shi the adjustabilityof any desired speed of the driving motor of the object with small 'energy consumption and with the elimination of non-productive movements at the individual adjusting stations. This end in view is attained by the drive of the'objects to be ad'usted'beiug efiected by the-differ ,fr ence of t e speeds of two rotating fields in the drivingmotor. Thisdifierence' i's pref-- crably attained, for'instance, by the regulation of the speeds of two generators op erated fiom the same source of energy by means ofa planetary gear. This stead of the twogeneratorstwo; rotatable sets of brushes on a single generator for producing the rotating fields, which brushes pose.

ing fields takes place in all cases at thecontrol stations, preferably by a: device for hi Stance, by a friction wheel which has no steps so that a jerkychangeiof the, 40 adjusting motion avoided. For con-' trolling the operation of this stepless regu 'Iation device, and in order to avoid inac curacies owingto slip and the like, auxiliary means, for pointers, telescopes and the; like may; ac-.

checking or supe cording to this invention-be provided driving devices as the objects'to be adjusted.

The regulation ofthe speed of therotating fields can take place" either byhand -or by automatically operating means, for instance well known gasgyroscopes.

motorsand simultaneously to move other objects located at a distance in 'corres'pondence withithe sum of the said individual movements.

are fed from 8" are not affected by any disturbances they will rotate at equal speeds, the magnetic rotating fields produced by them in the differential motor 9 will be equal and the motion of the rotor 9" is zero. If, however, the fields of the motor are made unequal as for example by. changing the relative speeds of the two generators by the regulating dc vice presently to be described, then the rotor the generator 8' (8" is keyed a bevel wheel (10") which drives by' a bevel wheel 11' (11") a shaft 12' (12" bevel W eels 13' (13") and 14' (14) the friction discs .Between these friction discs rotates a fric- ,tion roller 16, which is adapted to be moved axially by means of a screwthreaded shaft 17 and a hand-wheel 18. When the friction roller 16 is in the central position which the effective radii of both friction discs 15 and15" are equalthe speeds of both generators are also equal. If, however, the friction roller 16 is displaced by means of the hand-wheel18 that generator connected with the friction disc whose effeetivefradius is the shorter will run fasterrwhile the other generator will run slower. Thedifi'erential motor 9 thus rotates in one or the other'di-- rection in' accordance with 'the adjustment of the friction roller' 16, and ata speed which is iproportional to the displacement of said ro r. v a

motor 9 1) or 9 (Fig. 7%

Fig. 2 illustrates an examp e of the manner of controlling a gun from the different tial motor 9. Upon the shaft of the rotor" is fixed a worm 27 "which gears with a seging wires and 55" with the differential ment 28 fixed upon the gun 29. The angle of elevation of the gun 29 is thus adjusted by means of the ent 28.

worm 27 and the toothed Fig. "3 illustrates an auxiliarv device for supervising the operation ofthe construc-- tions shown inFigs. 1 or '7'. IA differential motor of small size is connected in parfriction roller 16 are mountedallel with differential motor 9 or 9 by means of the wires 55 and 55". Theworm 31mounted on its shaft consequently turns Upon the wheel 36 is fixed a counter-pointer or mark 35. Above the wheel 36 designed as receiver of a transmission system travels a main pointer 32 which is remotely controlled by a transmitter," not illustrated, by means of the conductors The pointer 32 is moved by the same amount which is to be adjusted by the motor 9'. If the pointers 32 and do not coincide the hand-wheel 18 (Fig. 1) must be turned until this is the case. Y

In the case where it is desired to check or supervise the adjustment or control of an object mounted on an oscillating platform so as to compensate for the oscillations of'the platform, the auxiliary checking device shown in Fig. 4 is preferably employed. It will be understood that this checking device may be used with either of the arrangements shown in Fig. 1 or Fig. 7. As shown in Fig. 4 a spur gear 46 is secured to the shaft 17 upon which the hand wheel 18 and This gcar' meshes with a co-o-perating spur gear 47 se cured upon one end of a shaft 48, which is for 'part of its length, provided with a screw thread. A second friction roller 49 is rotatably mounted upon a nut which has its borescrew threaded for engagement with the screw threads of the shaft 48, and said roller 49 is in engagement. with a cylinder 52 secured to the armature shaft of a,constant speed motor 50. w The motor 50 is energized from a suitable source of current and serves, through the action of the cylinders ;52, to drive the friction roller 49. The frictionroller 49'is also in engagement'with a friction disc 51 and serves to rotate the latter. A telescope 45, mounted on a support which oscillates in unison with the oscillating platform. is operatively connected with thefriction'disc 51 by means of' the worm segment- 44 secured to the fulcrum of the telescope, a worm 43 in mesh with said segment and the bevel gears 53 and 54. With thisydevice it vwill be obvious that as the hand wheel'18- is turn d to adjust the roller object being controlled. The motor 50, as

heretofore pointed out-rotates an constant speed and by'means'of the friction wheels 52, 49 and 51 drives-the bevel gears 53, 54, thus moving-the telescope 45 which serves "as! a checking or supervising device, -so that observations made by means of the telescope can be used for checking against the proper v operation of the object mounted on the oseillating platform. Adjustment of the hand of theroll 16 serving to regulate the opera tion of the main driven. member, for example, the gun 29, while adjustment of the roll 49 insures a similar operation of the checking or supervising telescope.- It will -be. remembered that thesfriction roll '16 is B caused to be rotated by the rotation, or

rather differences in the speed of rotation, of the friction discs 15', 15 and that as the friction roll 49 merely acts as an idler. the friction roll 52and motor 50, or any other device which rotates ata constant speed. is needed to produce the rotation of the idler 'friction roll'49 and the friction disc 51. A modified construction of a device similar to the one shown in Fig. 4 is illustrated in ig. 5 and consists in the provision of a differential motor 42, secured-by the worm Wheel 43, and worm segment 44, to the telescope 45, upon the fulcrum of which the segment 44 is secured in the same manner as shown in Fig. 4. The motor 42 is connected friction roller 16' shown in. parallel with both the stator and rotor of the motor 9 (Fig.1) by the conductors 56' and 56-. With this arrangement it will be seen that the diiferential moto 42 will move in unison with the motor 9 so that the movement of the telescope and the-object to be controlled, for example, the gun 29, will be the same. The construction shown in Figr. 5 is'pa-rticularly applicable where it is desired ito have an observer. located at a distance'from the operatorofthe hand wheel '18,-c-heck or supervise the adjustment ofthe "a gyroscope'68, which transmits its motion by means of bevel wheels 69, to a shaft 72,

upon which acentrifugal governor 71 is mounted. Upon the sleeve 73 of the governor which moves axially when the shaft 72 is rotated, the friction roller 16 (Fig. 1 is fixed and. if now, as assumed, the shaft 72 is rotated from the gyroscope 68 in corresr-ondence with the rollin motion of the ship, the friction rollen '15 will, if the regulatin; gear is properlys designed, be displaced axiallv by such a distance, that it automatically adjusts the operative radii of the friction discs 15', 15" inthe same man ner, would have been donethe system to Fig. 1 by turning-the handaccording wheel 18.

If it is desired a; transmit 'a pIuralit-y of 3" adjustments to thesa'me object, thismay be etiected by multiplying the arrangement shown in Fig. 1. Preferably the simplified arranfzeuentillustrated .Fig. '7' should, however, be employed such a case. In this fisnu'e it has been assumedg' by way of example, that certain adjustmentsshould simultaneously Jae transmitted to A and B, which adjustments may differ from each othelg'and to a third place C the sum of these two single adjustments. The devices. for controlling the operations fully ex} plained in the Figures 3.6.are also diagram matically illustratedin this Figure 7. -A motor 1 of constant speed directly drives a generator 8* mounted on its shaft 8". This ,-generator feeds by the-lines 37 the stator gun 29 mounted on n16 deck of a ship is to becontrolled, the telescopema v be located in an observation mast or any other part of-the ship. while the control handle 18 may be located in the'gun turret, below decks, or

The differential motor 9 connected with the three-phase generators 8 and 19 then turns the counter pointer 21 in correspondence with the sum of the movements of the, counterpointers 21 and 21 If, on the other hand, it is' only necessary to telecontrol a remote object according to the sum ordifierence of a: plurality of-individual movements, the system shown in Fig. 7 may be considerably simplified. In such a case the system of- Fig. 1 suflices. The friction roller 16 of Fig.. 1 is then adjusted by means of the hand wheel 18 by such an amount that the object to be controlled is moved by the motor 9, at an amount corresponding to the predetermined sum or difference of the plurality 'of individual movements.

In some cases it will be desirable to provide means for the adjustment of the friction roll 16 from-a distant station. In such cases any well known automatic device, such as themotor or the receiver of a distant control transmission system, may be geared to the shaft 17 so as to be used alternatively. for adjusting said roll in place of the'hand wheel 18", such a. device is indicated diagrammatically at Din Fig. 7 of the drawmgs. r I X In order to further simplify the; mecha-' nism according to this invention an arrangement may be employed as illustrated inFig.

8 or Fig. 9. Instead of employing a genera- I tor for the generation of each rotating field which is connected with agbevel wheel 10 as in Fig. 1, and thus two altogether different generators for the remotecontrol of the driving motor ofthe object to be adjusted,

the system according to Fig. 8' enables a single generator to suffice-for all cases. A source ofpower ,a (a motor, clock-work or the like) rotates'with constant speed a friction disc bf which by means of a friction roller 0, adjustable by means (if a hand-wheel (.Z, rotates a friction disc 6 The enlarged perspective detail of Fi 8 shows more clearly thepconstruction of the parts by which the single generator is con-- nected to the friction wheel 6 and the parts by which the speed of the differential motor is controlled. As shown in Fig. 8 the armature shaft of the differential motor is constructed of a plurality of'laminate'd, alter nately arranged, conductors and non-conductors, each conductor being in circuit with an armature coil. 'Arranged concentrically of the armature shaft is a pair of sleeves 'v, w, of insulating material which sleeves have secured to the exterior thereof a plurality of contact rings s, at, respectively, withwhich the exterior brushes h, i, engage. Securedto the interior of the sleeves v, w are the inner brushes Er, 1 which engage the. laminated armature shaft,'each brush it, or 3 being connected by a connecting wire with ,its respective ring 8, or u. The sleeves 4;, 'w,r are PI'OVIdBd with spur gears 12, 9, respectively, with which mesh the spur gears 9 'f mounted, respectively, on the shafts which Y carry the bevel gears 9 f and the latter meshing with the bevel gear e secured to the shaft upon which the friction wheel I) is secured.

The set of brushes 7:. feeds the'rotor winding m of the same difi'erential motor by means of the wires M, n and n*.- The motor is in this figure shown in star connec- The motionof the friction disc 6 i s trans- "mitted by means of gear wheels e ft, 2

When the relative position of the sets of brushes is changed by an axial displacement of the friction roller 0 by meansof the hand-wheel d the motor m. starts rotating in correspondence with the movement of the sets of briihes, which for instance by the mechanism shown in Fig. 2, can be trans .10 mitted to any object which is to be adjusted. If it is desired to avoid'the provision of two movable sets of brushes on one generator, the construction illustrated 9 maybe employed. Herea motor a drives by -1 neans of a regulablefriction-drive b 0, d, 6 directly 'thesct of brushes 21 which is arranged inan auxiliary deviceo constructedin the manner of a. direct current dynamo :and

. which is fed from the generator 70' by conductors 2 2 and 2 The set of brushes again consists of brushes displaced in relationto each other by an angle of 120.which ghde over contact rings o 0 .0 of the auxiliary device. This auxlliary device-is connected 25 with the rotor m of the ,difi'erential motor m-by conductors t, t and t. The stator;

winding" m of the motor m.is fedfrom the generator I: by means of conductors n, n and n When the brushes z are at rest the motor m also stands still since its stator and rotor winding arecfed by current of equal frequency. If, on the other hand on turning the set of brushes in consequence of the'displacement of the friction roller 9 .by means of the handdvheel d, the speed of the rotor field is changedin relation to the stator field in one or theother sense, the motor rotates in correspondence with the difl'erence of the speeds of the two rotating fields. 4 The control or supervising devices-illustrated in the Figures 3, 4 and 5may obviously equally well beemployed inarrangements;

accor to theFigures'7, 8 and 9. This also hol ood for the automatic regulate ingFdevice or the friction drive illustrated It be readily understood, that of the auxiliary supervising mechanism, such as thetelescopes 45, illustrated in Figs.
